Broken capacitor C60 when removing light engine

David Eriksson

Dear Forum,

Thanks for a very organized forum!

I think I managed to break the capacitor C60 when I removed the Light Engine :-(. Does anyone know the specifications of capacitor C60? It is located at the lower board on Lighcrafter next to one of the two screws that holds the small vertical green board on to which the DMD sit.

For other people who wants to remove the light engine: I would suggest a small adjustement to the "LighEngine" description in this forum.

Unscrew not only light engine from base plate, but also both boards. Then one can just pull out the light engine (given that both ribbons are disconnected!). Once this is done there is no C60 in the way for the screw, and that screw can be easily and safely removed.

Best regards,

David

David,

The capacitor you need to replace C60 with is a 1uF capacitor with a voltage rating of 25V. Did the pads come off with the capacitor? If they did, you can solder the replacement capacitor to the C59 pads.

For reference, all component values are available in the LightCrafter schematics. These are available on the TI LightCrafter website in the Technical Documents section. http://www.ti.com/tool/dlplightcrafter

Regards,

Blair

EDIT: In addition to the schematics, you can also find LightCrafter's BOM in the DLP LightCrafter EVM Reference Design v2.0 in the Available Versions section on the TI LightCrafter page. http://www.ti.com/tool/dlplightcrafter

Hi Blair,

Great! Actually it turned out that I hadn't destroyed it completely (it was more a scratch on the surface of the capacitance).

Thanks a lot!
